1992-015A
STS-45 flew the Atlas-1 Spacelab Earth observation mission, which included UV auroral imaging and SEPAC electron beam tests. ATMOS and GRILLE observed aerosol bands from the Mt Pinatubo eruption.
The vehicle was a little slow at MECO because the flight software ignored an inclination-dependent effect. An OMS-3 burn a couple of hours later raised the orbit, making up the underburn.
